CTD 30 seconds after loading flight...graphic card error

Hello,
I’m new here, just bought 10 days ago the MSFS and everything worked perfectly. I have installed only one 3rd party airport Brussels and tried Littlenavmap (but not using it)…I have RTX3090 and after the last NVIDIA update I get random CTD (after 30min, 20min, some times earlier or later) under safe mode too and it’s always the same message that “your graphics device has encountered a problem and the application will close. This may be due to graphics card overclocking, overheating or due to a driver fault”…Is there a solution yet for that or we have to wait for the next Nvidia update? Thanks for sharing if you have any information…
Rgds, Boris
